Protein

Dr. Andrew Huberman Recommends ~1g/lb, Whole-Food First

Huberman's clearest own-voice protein guidance is a general target of ~1 gram per pound of body weight, mostly from whole foods, with whey superior to collagen for muscle due to higher leucine and bioavailability. His muscle and brain episodes lean on EAAs/leucine, and guest Gabrielle Lyon reinforces the muscle-centric, ~1 g/lb-of-ideal-bodyweight position.

The first question for today's AMA is quote, "is there a distinct health advantage to using bone broth or collagen protein versus whey protein?" I get this question pretty often, and I touched on this in the episode that I did with Dr. Lane Norton. But I think the key thing to remember here is that while protein is one of the three macronutrients, proteins, carbohydrates, and fats, not all proteins are created equal. Now, what differentiates different protein sources has a lot to do with how easily those proteins are assimilated into our body and their amino acid content.

Dr. Peter Attia 1.2-2g/kg + Resistance Training

Attia has the deepest, most quantified coverage across many episodes (Layman, Norton, Allison, Kaeberlein). He treats the RDA as a floor, targets 1.2-1.6 g/kg and aims near 2 g/kg, and argues higher protein becomes protective after 50-65 because sarcopenia and frailty dominate human aging — unlike the mouse mTOR-lifespan findings. He also debunks the kidney-damage fear as lacking clinical-trial support.

Dr. Rhonda Patrick 1.2-2g/kg; Exercise Resolves the IGF-1 Concern

Patrick's dedicated solo synthesis episode lands at 1.2-1.6 g/kg general and up to 2 g/kg for recomposition, calculated on ideal body weight and safe for healthy kidneys. She is the core expert who most directly resolves the longevity tension: higher protein raises IGF-1, but exercise redirects it toward muscle and brain. She also platforms guests Van Loon, Phillips, and the low-protein counter-view of Valter Longo.

…0.54 to 0.72 G per pound this is based on alternative methods like stable isotope studies which consistently show that higher intakes are necessary to maintain a positive protein balance far above the 0.8 G per kilogram often cited so aiming for at least 1.2 gr and up to 1.6 G is what we're talking about for optimal protein intake there's good evidence to suggest this for example older adults consuming at least 1.2 grams of protein per kilogram body weight per day prevented age related losses in lean mass when compared to consuming the RDA of 0.

Bryan Johnson Plant-Forward; 1.2-2.2g/kg for Bone

Johnson is the thinnest core source on protein and the only non-quantified-for-longevity voice. His Blueprint meals are plant-forward (lentils, chickpeas, hemp/pea protein) plus collagen, at a ~25% protein macro split. His single stated g/kg figure (1.2-2.2 g/kg) comes from a bone-health video, and he emphasizes protein plus strength training for muscle and bone — agreeing protein matters without holding the muscle-maximalist position.

Dr. Mark Hyman Eat More Protein, with mTOR Balance

Hyman has an own-voice episode arguing you need to eat more protein for longevity (30-40 g per meal, protein and fat before carbs, protein-rich breakfast), while hedging that a balance is needed on mTOR. His corpus is the conflict in microcosm — he platforms the strongest high-protein guests (Lyon, Layman) and the strongest low-protein guest (Longo).

…multi-gram amounts so we need you know probably 30 to 40 grams a meal maybe 90 to 120 180 grams a day depending on your size so this is a very interesting thing so the question is you know what does protein do well why do we need so much of it well it's it's an essential nutrient because it's the stuff we're made of right we make proteins that's all your DNA does the DNA is very simple it basically transcribes the sequence of amino acids that are needed to build a particular Protein that's all your DNA does so it assembles amino acids to proteins proteins are the structural…

What do experts agree on about protein?

4 of 5 experts actively recommend more protein than the 0.8 g/kg RDA — converging on roughly 1.2-2 g/kg paired with resistance training (Johnson's coverage is thinner and plant-forward). The 'high protein shortens lifespan' fear traces mainly to guest Valter Longo's low-IGF-1 view; the core experts largely resolve it by noting that exercise redirects IGF-1 toward muscle and that sarcopenia — not mTOR — dominates aging risk after 50.

Where do the experts disagree on protein?

Is protein the longevity lever or a risk to manage? Attia, Hyman, and guest Gabrielle Lyon take the muscle-first higher-protein view; guest Valter Longo argues for low protein to keep IGF-1/mTOR low. Animal vs plant for longevity: Attia and guests Layman/Lyon push animal protein for EAA efficiency, while Johnson's Blueprint and Longo are plant-forward. Is there a per-meal anabolic ceiling? Attia questions the rigor of the 20-30 g 'threshold,' while Van Loon and Lyon still recommend per-meal dosing of ~20-30 g.

How strong is the expert consensus on protein?

The consensus on protein scores 3.7/5 — a strong level of agreement across Huberman, Attia, Patrick, Johnson, and Hyman, based on their public videos.
